FREDERIC MAHOUDEAU, OF NEW YORK, N. Y., ASSIGNOR TO THE AMERICAN SUGAR REFINING COMPANY, OF SAME PLACE.

AUTOMATlC STOP FOR SUGARUORYINGAPPARATUS.

SPECFIOATION forming part of 'Letters Patent No. 678,747, dated July 16, 1901.

Application filed January 4, 1901. Serial No. 42,142. (No model.)

To @ZZ whom t iii/ty concern.:

Be it known that I, FREDERIC MAHOUDEAU, a citizen of the Republic of France, residing at New York city; county and State of New York, have invented a new and useful Improvement in Automatic Stops for Sugar-Drying Apparatus, of which the following is a specification.

My invention relates to an automatic stop designed to be employed with drying-furnaces for sugar or other bodies.

The furnace employed for drying sugar and similar bodies consists of an oblong chamber and two parallel trackways. Sugar is put into the baskets and the baskets vmounted upon the upper trackway. Then through suitable apparatus the baskets are moved to the end of the furnace, carried downward to a lower trackway, and moved out of the furnace. The movement of the baskets through the furnace is usually continuous.

My invention has for its object to automatically stop the movement of the baskets through the furnace should a workman at the end of the furnace not be in a position to receive the outcoming baskets or for other reasons.

The accompanying drawings will serve to illustrate my invention.

Figure l is a side elevation of a furnacechamber and automatic stop, a portion of the trackways, basket, and means for moving the basket being shown in dotted lines. Fig. 2 is a longitudinal section through a wall of the furnace-chamber and a plan view of the stop mechanism. Figs. 3 and 4 are enlarged elevations of a portion of the stop mechanism. Figs. 5 and 6 are respectively enlarged end and plan elevations of portions of the stop mechanism.

In the drawings, A represents a furnacechamber, B B parallel trackways, and C an endless link belt carried over wheels D D at opposite ends of the furnace-chamber. Mo-

tion is imparted to the endless link belt through the belts E and F.

G represents baskets (for carrying the sugar or other body to be dried through the furnacechamber) provided with the upwardly-extending arms H, carrying bearings l, on which wheels .l are loosely mounted. The baskets Gr move upon the trackways B Bby motion imparted to them through an endless link belt O.

Mounted upon and secured to the inner end of a shaft K, which is supported by and moves freely in a tubular bearing L on a bracket M, is a depending arm O. Mounted on and secured to the other end of the shaft K is a counterweight P and a handle Q.

R is a rod mounted to reciprocate horizontally in guides S. The forward end of this rod is connected to the counterweight P by means of the pin T, located in the slot U in the shaft of the counterweight. The opposite end of the rod R is connected to one arm of the bell-crank V, which is pivoted at XV. The other arm of the bell-crank is connected to the belt-shifter X, between the upwardlyprojecting arms of which Il is included the belt E.

Yrepresents fixed and loose pulleys mounted upon the shaft Z.

The operation of the device will be readily understood. When the parts are in the position shown by the full lines, Fig. 5, the depending arm O is in the path of movement of the bearings I of the baskets G. The bearings I, by the forward movement of the carriage, impinge upon the arm O, pushing it forward. The motion will be transmitted to the rod R, which shifts the belt E from the fast to the loose pulley Y on the shaft Z. When it is desired that the movement of the baskets through the furnace-chamber shall be uninfluenced by the stop, the handle Q is pulled outward to the position shown in the dotted lines, which removes the arm O out of the path of movement of the carriage and the carriage can freely leave the chamber.

Having thus described my invention, l claiml. In a furnace for drying sugar or other bodies, the combination of the trackways, a moving carriage, means for moving the carriage, a pivoted arm in the path of movement of the carriage, a rod moved by said arm, and a belt-shifting device actuated by said rod.

2. lna furnace for drying sugar or other bodies, the combination of the bracket carrying a tubular bearing, shaft with. depending IOO arm, counterweight on opposite ends of shaft, rod connected to said counterweight, and bell-crank and belt-shifter connected to said rod.

3. In a furnace for drying sugar or other bodies, the combination of two pairs of paraliel trackways, a moving carriage, means for moving the carriage, a pivoted arm in the path of movement of the carriage while on the lower trackway, a rod moved by said arm, and a belt-shifting device Iactuated by said rod.

4.-. In a furnace for drying sugar or other bodies, the combination with two horizontally-disposed trackways, one in the upper part of the furnace-chamber and one in the lower, a number of moving carriages, mechanism for moving said carriages, and a de- Vice in the path of movement of said carriages and at the exit of the furnace which, when actuated by one of said carriages, will stop the movement of al1 of said carriages through the furnace.

In testimony whereof I affix my signature in the presence of two witnesses.

FREDERIC MAHOUDEAU.
